Never have threesome with your colleague

I would tell a personal experience of mine to demonstrate that why you shouldn't have a threesome hookup with your colleague. I yesterday just had a threesome hookup with a colleague of mine. The next morning, the whole company knew that I had a threesome with her. It was so embarrassed. I never thought that she would be so not discreet. If I knew that earlier, I would rather risk the chance of catching STD to have a tinder threesome than having a threesome with her.
